I just finished listening to the Christian Audio version of The Explicit Gospel by Matt Chandler with Jared Wilson.
Of all of the books that I've read on the Gospel in the last few years, I would rank this one near the top. Matt Chandler does an excellent job of explaining the Gospel in an... well... explicit way. He describes the Gospel in the broader perspective as the "Gospel in the Air" and the "Gospel on the Ground" is the more personal aspect of the Gospel. He then discusses the dangers of focusing on one aspect of the Gospel without taking into account both the big and the small picture of what God is doing.
I especially appreciated his personal approach, sharing stories and experiences that illustrated different aspects of the Gospel. In many of his stories he was willing to share how he had struggled or gotten it wrong in the past; times where he had shared the gospel in not-so-perfect ways, but God's grace was even in those events of his life, as he so adequately shares. One story he titled, "The Dirty Rose" was especially touching.
If you have questions about the Gospel or you are simply desiring a deeper understanding of the Gospel, then this is a good book for you.
David Cochran Heath, the voice talent for many of Christian Audio's works, does an excellent job of reading through this book. In my opinion, a good voice talent will cause you to forget that you are listening to an audio book, and it will feel more like you are listening to someone talk to you while you are driving down the road.
